Before this overlay would happen only for defined rectangle area,
now it's possible to show current / reference frames only, which
makes it possible to do more real slit view involving even displaying
frames on different monitors.
Still some work need to be done to clean interface up and support
displaying color information for reference shot.
space works again
This commit restores the support for using Grease Pencil in the Sequence Editor
image preview region, making it possible to scribble on footage for review
purposes again. Due to internal changes in how the Sequencer handles the image
drawing for this stuff (i.e. it is now fully based on View2D instead of trying
to implement its own little crazy offset+zoom stuff), a lot of the old code for
handling those offsets is no longer needed. Instead, one of the "standard" cases
is now used, and works quite well.
Bugfixes:
* View-space Grease Pencil drawing was done in wrong place (before view2d
restore)
* Grease Pencil entry in RNA had wrong/missing type
Credits:
* DingTo - initial patch/attempt at restoring support
* Aligorith - solved the "offset problems"
* Remove all code for Texture and Sequencer plugin system, this never worked in 2.5x / 2.6x and is therefore not needed anymore.
* DNA structures are kept, all read/writefile code is gone.
... instead add scene.sequencer_editor_create / clear, these match id.animation_data_* functions.
- refactor for names, for scene level functions call them BKE_sequencer_*
This adds movieclip input support to the sequencer, thereby making
undistorted and stabilized footage available without a seperate render step.
Also: removes some old cruft code from the sequencer:
* new_tstripdata wasn't used anymore
* StripElems were allocated for SCENE strips on full length, wasting memory
Added a comment, that hopefully makes things a little bit clearer:
StripElems are *only* usefull for MOVIE + IMAGE strips for all other strip
types one can set this pointer to NULL. (If that should cause otherwise
problems, then the code that doesn't check for NULL is to blame!)
Crash was caused by attempting to create strip text from a missed sound datablock.
Actual error happened when this sound datablock was missed, but crash isn't nice
anyway and there were no way to repair scene.
- use more logical names for strings, noticed too many strings called `str` when reviewing name patch.
- pass __func__ macro to uiBeginBlock(), quite a few names were wrong (copy/paste error).
- make ortho grid drawing use vertex arrays
- make perspective view floor drawing cache result of UI_ThemeColorShade so its not called on every line.
- make perspective view floor only loop once on each axis when the grid floor isnt being drawn (was looking over all grid lines for no reason).
- add UI_GetColorPtrShade3ubv() to replace UI_GetColorPtrBlendShade3ubv() when no blending is needed.
